Andy Hackbarth is living in Nashville and pursuing the dream of becoming a country music star, but when summer turns sweltering in Music City, the first thing on his mind is the cool Colorado air and the baseball played by his beloved Rockies.

Hackbarth grew up in mountain towns in Colorado and fell in love with baseball. He played through high school and up until he blew out his arm his freshman year in college. He traded a leather glove for a guitar and has been writing songs ever since, and his latest one, "We Ain't Done Yet," was written specifically for the Rockies team that he's come to know and love since the franchise began in Denver in 1993.

Hackbarth said he started writing the song simply from the inspiration this band of unlikely stars has given the long-suffering Rockies fans. Once the club won 21 of 22 games on its stunning run to the World Series, Hackbarth rushed to get the final mix done.

And then, when the team lost Game 1 of the Fall Classic to the Red Sox by the ugly score of 13-1, he rushed it even more.

"The song was created more from the regular season," Hackbarth said. "But it really fits now, too, because even though we went on the big run, people didn't give the Rockies the credit they deserved. To do what they did, the players and the fans had to believe that we ain't done yet. We're gonna do what it takes to get to the end, and that certainly was the World Series that I had in mind."

The lyrics are straightforward and easily recognizable to any Rockies fan.

"Welcome to the West, welcome to the big show, this Rocktober Wild Card run/Welcome to the spotlight, to a touch of the old times, that mountain baseball fever high," Hackbarth sings. "'Cause we're old school with young guns, defense and home runs, that ball is gone and it ain't comin' back.

"We ain't done yet, we ain't done yet/Helton and the boys are gonna do it again. We ain't done yet, we ain't done yet/Let me hear you say, we ain't done yet."

Hackbarth said the original title for the song, conjured with the help of his Rockies-fanatic father, was "A Touch of the Old Times," because of the team's throwback style.

"My dad and I always talked about how this Rockies team is bringing baseball back for a lot of people, and not just in Colorado," Hackbarth said. "They developed these players on a smaller payroll, they're nice guys, they get along, they don't bicker, there are no drug problems, so yeah, it's a touch of the old times.

"What was so cool about this team is old-school baseball. That's why people are rallying around them. It's just a really cool team and I feel like there's nobody that's more deserving. Rockies fans have had pretty dismal seasons over the years, but the fans for the most part have been really supportive and positive."

And now that the Rockies are in the World Series and find themselves up against a wall heading home for Game 3 at Coors Field, Hackbarth said he has an idea of what needs to happen to turn it around.

"I feel like we just have to get the bats going," Hackbarth said. "We have great young players we've developed, and they're good hitters. It was kind of hard to watch Game 2. It was frustrating, because it seems like they're timid up there, not swinging with the confidence they had in the regular season. It's time we got hot with the bats."

Meanwhile, Hackbarth is getting hot with this song. He's hoping to take the exposure he's getting and turn it into radio play for his upcoming album, which he's putting the finishing touches on in the studio in Nashville.

"It's huge for me," he said. "Tons of people are hearing it and people are calling me from (Colorado) saying they're saying my name on the radio. It's really exciting, a really big step for me. The whole thing has exceeded my expectations, but the coolest part of all of it would be for the fans to hear it (at Coors Field), in that setting under the lights, that would be the ultimate for me."

OK, maybe not quite the ultimate.

"I would take them not playing that song one more time ever if it meant the Rockies winning the World Series," he said. "And I still think they're gonna do it. They're gonna come back because that's the kind of team they are.

"And if they don't, you better watch out next year."
